Snooki told US Weekly: 'My dad was upset. He said, "You have your whole life ahead of you." He came around eventually, and now he can’t wait for the baby. My mom is so happy for me.'

Jionni added that the couple 'are not going to screw this up.

The parents-to-be, both 24, have been dating for about a year and a half.

The spray-tanned couple have not announced a wedding date, but their baby is due late summer.

The pint-sized star says that their wedding won't be for at least a year, as she wants to have time to lose her baby weight before walking down the aisle.

Surprise! Snooki arrived at her fiance Jionni Lavalle's parents' home for an engagement/baby party on Friday night in East Hanover, NJ

Armed with a $55,000, 5-carat princess-cut engagement ring, Jionni originally popped the question on a balcony at the W Hotel in Hoboken.

Jionni, who makes his fiancée pickle pancakes, is currently working on earning a teaching degree just like his older brothers.

Jionni already gave his baby on the way a peculiar nickname on Twitter: 'Nicole and I are real excited!! Our baby is going to be #ShortnTan.'

It already looks like 'ShortnTan' is going to have a lot of famous aunts and uncles courtesy of The Jersey Shore.

Her other BFF Deena Cortese told Ryan Seacrest on his KIIS-FM morning show last Friday that she is going to spoil 'the little guy.'

I think Nicole is going to be a great mom,' Deena said. 'She's a very genuine person and her heart's always in the right place. She always puts people before her.

'This has been her dream – getting married, having kids.

However, Deena added, 'I'm going to miss my little partner-in-crime.'

Her former flame Vinny Guadagnino told The Huffington Post that people should not judge the new mother based on her hard-partying past.

'Any mom, whether they're 40 or 24, doesn't know what it is like until the baby is there. Everyone can talk about how irresponsible she is and how she drinks, but you don't know how she'll be when the baby comes out,' Vinny said.

As for what kind of father Jionni will be, Vinny had this to say: 'I don't know the kid, but it is going to be a life-changer for him. They have good families so they have people to help them.'

Snooki and JWoww have spent the past two weeks filming their new spinoff Snooki and JWoww vs. the World.
